Description

You're trapped in a hostile facility overrun by alien creatures. Move through the corridors, find and shoot every enemy before they reach you. Survive long enough to clear the level.

Controls: up to turn left, down to turn right, middle button to move forward. Press both side buttons at the same time to shoot. Collect medkits to restore health. Your kill count is tracked, try to beat your best score.

That's it. No story, no cutscenes, just you and whatever's coming around the corner.
